Editorial.

Dear colleagues, It is my great pleasure and honor to introduce the September 2017 Issue of Ultrasound International Open (UIO), already in its eight number from the initial appearance of the journal in 2015. Recently, UIO has reached the antechamber of journals applying for Impact Factor, being accepted in ESCI (Emerging Sources Citation Index). Consequently, UIO will soon appear in the Web of Science, a major step forward for the journal. The enthusiasm and hard work of the editors, as well as of the entire Thieme support team was invaluable for this endeavor! Three landmark papers are published in the issue, along with 4 case presentations and 1 letter to the editor.
